Proteomics is a scientific discipline that involves the comprehensive study of proteins in a biological system. It aims to understand the structure, function, and regulation of all the proteins present within a cell, tissue, or organism, collectively known as the proteome. Proteins are vital macromolecules that carry out numerous essential functions in living organisms. They act as enzymes, receptors, structural components, signaling molecules, and more, playing a fundamental role in almost all biological processes. The field of proteomics employs various techniques to analyze and characterize proteins: 1. Protein Identification: One of the primary goals of proteomics is to identify and catalog all the proteins present in a given sample. Advanced techniques like mass spectrometry are used to determine the mass and sequence of protein fragments, enabling researchers to identify specific proteins. 2. Protein Expression Profiling: Proteomics can be utilized to compare protein levels betwe...
